In this sentence,
Which of those would you like?
Here is what I understand that words like ''which" and "none" are singular and can be plural. The word "which" is a relative pronoun that is plural because the demonstrative pronoun those is plural.
However, I think the noun "you" is singular and the verb "like" is singular and "would" is a helping verb that is past tense (neither singular or plural and "you" is singular).
The general rule is that if you use a singular noun you must use a singular verb and if you use a plural noun, you must you a plural verb.
My main question is:
Why doesn't the general rule apply to the sentence above and a plural noun as well as a plural verb is used instead of a singular noun and verb?
